WILLIAM s. HAMM, or HUBBARD WOODS, ILLINOIS, ASSIGNOR To THE ADAMS &

LAMP-CHIMNEY HOLDER.

To all whom it may concern:

Be it known that I. IVILLIAM SIIAMM, a citizen of the United States, andresident of Hubbard Woods, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Lamp-Chimney Holders, ofwhich the following is ai specification, and which are illustrated inthe accompanying drawings, forming a part thereof.

The invention relates to holders for lamp chimneys, and is herein shownand is especially applicable to lamps known as longtime burners andcommonly used for signaling purposes by railroads, as in connection withswitches.

The object of the invention is to provide improved means for holding thechimney; and it consists in a structure such as hereinafter describedand as illustrated in the accompanying drawings, in which Figure 1 is aplan view of a burner with the improved holder applied thereto;

Fig. 2 is a side elevation of the burner with the chimney in place; and

Fig. 3 is a detail of one of the elements of the holder.

The burner shown in the drawings is of known construction, comprising abody portion 10 and a wick tube 11 provided at its upper end with aflame spreader 12. The usual gallery 13 is present, and it has thegeneral form of a flat ring supported upon standards 14: rising from thebody 10. Spring fingers, as 15, 16, project upwardly from the gallery 13and impinge upon the chimney 1!.

The chimney is shown as having an annular channel 18 near its lower end,and the fingers 15, 16, are bent inwardly to form an elbow 19 forengaging in this channel. Preferably the spring fingers 15. 16, areformed in pairs of a single wire, the crossmember 20 uniting the twofingers being secured to the gallery 13 by means of an overturned lip 21integral therewith. At the juncture of the cross-member 20 with each ofthe fingers 15, 16, the wire is coiled to the form of a helical spring,as 22, for urging the upper ends of the fingers toward the chimney.These helical springs project under and bear against the gallery,thereby preventing any turning movement of the cross-member 20 withinthe lip by which it is held. The upper end of each of the fingersSpecification of Letters Patent.

is overturned outwardly to form a loop, as

shown at 23.

As thus far described the device presents no novel features, but isinefficient for holding the chimney in place when the lamp is su jectedto any violent jars or movements,

vsuch as occur in connection with railway switches. It frequentlyhappens in this service that the switch is thrown with a quick action,the operating lever being abruptly stopped at the completion ofmovement. A lamp mounted upon the switch staff is turned therewith, andthe quick movement and its abrupt termination is liable to dislodge thechimney from the holding fingers described.

In order to prevent such displacement of the chimney a spring wire 24 iscoiled to circular form, its end portions overlapping, and is threadedthrough the loops 23 of the several upstanding fingers. The ends of thiswire are bent outwardly, as shown at 25, 26, to form grips or fingerpieces which, when pressed together, expand the body of the wire ring241. Normally this ring is urged by its own elasticity into theshoulders 19 of the upstanding fingers and consequently enters into thechimney channel 18. In order to insert the chimney the finger pieces 25,26, are pinched together to expand the ring 24., and downward pressureof the chimney forces the upright fingers apart and permits its entrybetween them. The chimney being seated upon the gallery, pressure uponthe fingers 25, 26, is relieved and the ring 241 fits snugly within thechannel 18 and securely holds the chimney against any possible danger ofdisplacement.

I claim as my invention-- 1. In combination, a lamp burner, an annularly disposed series of fingers rising from the burner for inclosinga chimney, each having a shoulder adapted to enter an annular groove inthe chimney, and a clamping ring surrounding the fingers andseatedagainst the shouldered portions thereof and comprising an elastic bandhaving its ends overlapped and bent outwardly lto form finger pieces.

2. In combination, a lamp burner, an annularly disposed series offingers ri ,ing from the burner for inclosing a chimney, and havingtheir upper ends formed into outstanding loops adapted to ente anannular groove in the chimney, a clamping ring of spring materialcarried within the gallery, a series of s rin fin ers rlsin from thetalzler and b b each having an instanding shoulder adj acent its upperend adapted to enter an annular groove in the chimney, such end beingoverturned outwardly to form a loop, an elastic Wire clamping ringlocated Within the several'loops and having its ends overlapped andprovided with finger pieces.

In combination, a burner having a chimney supporting gallery, a seriesof from the gallery and each having an insta-nding shoulder adjacent itsupper end adapted to enter an annular groove in the chimney, such endbein'g overturned outwardly to form a loop,

spring fingers rising and an elastically contractible clamping ringlocated within the several loops.

5. In combination, a lamp burner, an annula'rly disposed series offingers rising from the burner for inclosing a chimney and each having ashoulder adapted to engage an annular groove thereimand an elasticallycontractible ring surrounding the fingers.
